TO ALL TO WHOM THESE PRESENTS SHALL COME Be it known that I, FERDINAND FISHER, of Cambridge, in the county of Middlescx, and State of Massachusetts, have invented a new and improved Steam-Heating andVeutilating Apparatus; and do hereby declare the following ,to be a full, clear, and exact description thereof, reference being bad to'the accompanying drawings, making part of this specification, and in which- Figure 1 is a top view; and

Figures 2 and 3 are vertical sections of my invention.

In the drawings, A denotes an. upright drum or closed vessel, composed of a cylindrical shell, a, and two heads I) b, a series-at air-tubes, c c c, 850., extending entirely through the drum and its head, the whole surmounting a shallow air-chamber, G. A steam-induction pipe, 02, being a continuation of the exhaust pipe of'the steam engine, communicates with the interior of the drum A through its upper head, an eduetion pipe, 0, somewhat smaller in diameter than the induction pipe, leading out of the drum on the opposite side of the head, as shown in fig. 3. The drum A is further supplicd w ith a water-escape pipe,f, leading out of its lower part, asreprcsented, this pipe being for the escape of water 'which may be condensed within the drum. An air-blower or blast engine,'B, of anyn'cll-known construction, is connected with a chute, g, leading into the air-chamber C below the drum A, motion being imparted to the blower by means of a belt connected with the engine. from which the exhaust stcam'is taken. Air may be taken into the blower from any part of the building in which it may be situated, or from the external atmosphere.

The operation of the above-describod apparatus will rcadily explain itself to persons conversant with-the operation of steam. The following brief description, however, will clearly explain it to others. The exhaust steam from the engine passes into the drum A through the induction pipe (I, and by means of the difl'erential diameters of the induction and eduetion pipes will be slightly compressed and circulated throughout its entire area. Coming in contact with the air-tubes c c c, the steam will be condensed and will give out its latent heat, which will' be conveyed by means of these tubes to any portion or portions of the building that it is necessary to heat. The blast of air through the tubes from the blower aids in distributing the passage of warm air over the building, and enables it to be carried horizontally toany required distance. Should the steam within the drum be only partially condensed, the excess will escape through the eduetion pipe 0 into the atmosphere, my purpose however, being to so regulate the air blast as to condense the whole of it. The apparatus thus becomes not only a means of economizing much heat which would otherwise be lost in the escape of steam, but of warming and thoroughly ventilating a building. The warm air imparted by'it is moist and soft, and highly beneficial to health. I would remark that the apparatus may be employed to good advantage, and with economical results, by the direct application of steam to it. I

I clam the apparatus above described for utilizing exhaust steam forthe purpose of heating, and for ventilating apartments or buildings, consisting of the tubular drum A, with its induction and eduetion pipes (Z0, and the blower or blast apparatus 13 combined and operating as set forth and explained.
